Compiling
配置：錯誤：C 編譯器無法創建執行檔
我正在嘗試將 apache 2.2.15 升級到 2.2.27。在執行從 apache2.2.15/build 獲取的 config.nice 時，我收到以下錯誤：
checking whether the C compiler works... no configure: error: in `/home/vkuser/httpd-2.2.27/srclib/apr': configure: error: C compiler cannot create executables我試圖在網上搜尋，但沒有運氣。我還通過執行一個小的 test.c 腳本測試了 c 編譯器，它執行良好。線上提供的解決方案很少，例如安裝’kernel-devel’包，但它沒有解決問題。我怎樣才能讓它工作？
以下是生成的 config.log：

根據您給出的輸出，您正在嘗試在 64 位系統上編譯 32 位版本的 apache。這是來自此處配置的輸入：
--host=x86_32-unknown-linux-gnu host_alias=x86_32-unknown-linux-gnu CFLAGS=-m32 LDFLAGS=-m32另請參閱確認這一點的輸出行：
configure:3629: checking build system type configure:3643: result: x86_64-unknown-linux-gnu configure:3663: checking host system type configure:3676: result: x86_32-unknown-linux-gnu configure:3696: checking target system type configure:3709: result: x86_32-unknown-linux-gnu這裡它使用 64 位建構系統，但使用 32 位主機/目標。再往下，我們看到：
ac_cv_env_CFLAGS_set=set ac_cv_env_CFLAGS_value=-m32該標誌告訴 gcc 生成 32 位對象。您的 C 編譯器無法生成執行檔的錯誤可能是由於不存在 32 位工具鏈造成的。
測試您編譯 32 位對象的能力
-m32您可以通過使用該標誌編譯一個小的 C 範例來測試這一點。// Minimal C example #include <stdio.h> int main() { printf("This works\n"); return 0; }編譯：
gcc -m32 -o m32test m32test.c如果此命令失敗，則說明編譯器無法建構 32 位對象。編譯器發出的錯誤消息可能有助於解決這個問題。
補救措施
- 為 64 位目標建構（通過刪除強制 32 位建構的配置選項），或
- 安裝 32 位編譯器工具鏈
